MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 776,401, dated November29, 1904.

Application filed May 5, 1904. Serial No. 206,557. (No model.)

To all whom it may concern:

Be it known that 1, JOHN D. A. JOHNSON, a citizen of the United States,residing at Omaha, in the county of Douglas and State of Nebraska, haveinvented certain new and useful Improvements in Mechanical Movements;

and I do declare the following to be a full, clear,

and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention is an improved mechanical movement for converting rotaryinto oscillating motion and adapted for use in connection with washingand other machines; and it consists in the construction, combination,and arrangement of devices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a vertical sectional view ofmy improved mechanical movement, showing the same in use on awashing-machine for imparting oscillating motion to the stirrer. Fig. 2is a detail sectional view of the mutilated oscillating gear. Fig. 3 isa detail perspective view of the same. Fig. 4. is a perspective view,with parts broken away, showing another form of washing-machine providedwith my improved mechanical movement for operating the same.

In the embodiment of my invention shown in Fig. 1 there is a verticalshaft 1, which is mounted in bearings 2 at the ends of the upper andlower arms 3, formed at the inner end of a bearing bracket or frame 5,which is here shown as secured on the cover 6 of a washingmachine. Thatportion of the shaft 1 which is between the bearings 2 is angular incrosssection, and on the same is mounted a mutilated gear 7 foroscillating movement with the said shaft and also for vertical orlongitudinal movement thereon independently thereof. The hub of the saidoscillating mutilated gear is formed with a recess 8 in one side, inwhich is disposed the spring 9,, which bears against and slides on theshaft and prevents the oscillating mutilated gear from rattling. Thesaid gear is provided with peripheral spurs 10, which extend partlyaround the same, and that portion of the periphery of the said gearwhich is not provided with the said spurs is formed withoppositely-extending lugs 11, the

opposite edges of which are curved or inclined reversely, so that theyconverge outwardly and form reversely-disposed cam faces or surfaces 12.To the lower end of the shaft 1 is secured an agitator or stirrer 13.The bracket or frame 4 is provided withbearings 14 for a shaft 15, whichwhen in operation is revoluble continuously in one direction, and ishere shown as provided at its outer end with the crank-wheel 16, wherebyit may be rotated. To the inner end of the said shaft is secured aspur-pinion 17, which is adapted to engage and disengage the spurs ofthe oscillating reciprocating mutilated gear 7.

The bracket or frame at is provided at points beyond opposite sides ofthe pinion 17, diametrically and in line with the shaft 1, with sockets18, in .which are secured longitudinally-adjustable. shafts 19 by meansof setscrews 20. On the outer ends of the said longitudinally-adjustableshafts are mounted tapto move the latter longitudinally on the shaft 1and to alternately engage the spurs of the mutilated gear with oppositesides of the continuously-revoluble pinion 17, so that the saidmutilated gear is turned partly in one direction and then in the reversedirection and im parts oscillating motion to the shaft and to theagitator, which is secured thereto. The longitudinallyadjustable shafts19, which carry the tappet-rollers, enable the latter to be adjusted tocompensate for wear thereof and of the cams 12.

In Fig. 4 of the drawings 1 show my improved mechanical movement at oneend of another form of a washing-machine, the latter being provided witha cylinder 22, mounted in a longitudinal tub or body 23, the saidcylinder being oscillated by the operation of my improved mechanicalmovement, as heretofore stated.

From the foregoing description, taken in connection with theaccompanyingdrawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion,

and the minor details of construction may be resorted to withoutdeparting from the principle or sacrificing any of the advantages ofthis invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a mechanical movement for converting rotaryinto oscillatingmotion, the combination of a longitudinally movable and oscillatingmutilated gear having radial peripheral studs extending partly aroundthe same and oppositely-extending lugs at that part of its perimeterwhich is not provided with studs, said lugs having reversely-disposedoutwardly-converging cam-faces; a revoluble spur-pinion having a fixedbearing, arranged at right angles to the mutilated gear and adapted tobe engaged and disengaged on opposite sides by the spurs thereof, andrelatively fixed tappets disposed diametrically on opposite sides of thepinion and alternately engaged by the reversely-disposed cams of themutilated gear to impart reciprocating longitudinal motion thereto.

2. In a mechanical movement for converting rotary into oscillatingmotion, the combination of a shaft mounted for oscillating movement, amutilated gear mounted thereon for oscillation therewith and independentlongitudinal movement thereon, said mutilated gear having radialperipheral studs extending .partly around the same andoppositely-extending lugs at that part of its periphery which is notprovided with studs, said lugs having reversely disposed outwardlyconverging cam-faces; a revoluble shaft, a pinion thereon rotatedthereby, arranged at right angles to the mutilated gear and adapted tobealternately engaged by the studs thereof on opposite sides, andrelatively fixed tappet-rollers disposed diametrically on opposite sidesof the pinion and alternately engaged by the revesely-disposed cams ofthe mutilated gear to impart reciprocating longitudinal motion thereto.

3. In a mechanical movement for converting rotary into oscillatingmotion, the combination of a longitudinally movable'and oscillatingmutilated gear having radial peripheral spurs extending partly aroundthe same, and oppositely-extending lugs at that part of its perimeterwhich is not provided with spurs, said lugs being reversely disposed,outwardlyconverging cam-faces, an oscillating shaft on which the saidgear is mounted for rotation therewith and longitudinal movementthereon,a spring bearing between said gear and said shaft to prevent the gearfrom rattling, and a revoluble spur-pinion having a fixed bearingarranged at right angles to the mutilated gear and adapted to engage anddisengage the spurs thereof, and relatively fixed tappets disposeddiametrically on opposite sides of the pinion and alternately engaged bythe reversely-disposed cams of the mutilated gear to impartreciprocating longitudinal motion thereto.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
